The molecular geometry of a molecule with a core atom that has five areas of electron density and precisely one lone pair of electrons is called a disphenoidal or seesaw molecular geometry.
What is meant by disphenoidal or seesaw molecular geometry?
- Four bonds are made to an atom in the center of a disphenoidal or seesaw-shaped molecular structure, which has overall C2v structural symmetry. The fact that it resembles a playground seesaw is how it got the moniker "seesaw." Tetrahedral or, less frequently, square planar geometry is produced when four bonds to a center atom are present.
- The core atom of a molecule with a steric number of 5 and bonds to 4 additional elements and 1 lone pair is said to be in the seesaw geometry.

Explanation:
Explanation:
P₄+O₂=P₂O₃; non-balanced
P₄+O₂=2P₂O₃; to add '2' on the right side; non-balanced
P₄+3O₂=2P₂O₃. to add '3' before O₂ in the left side; balanced
Answer:
1s2 2s2 2p6 3s2 3p6
Explanation:
Calcium is the 20th element. It has 20 electrons in it's neutral state. The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6 4s2
However in the compound; calcium chloride, it does not exist in it's neutral state.
CaCl2 --> Ca2+ + Cl-
In Ca2+ state, it has lost two electrons, The total number of electrons becomes; 20 - 2 = 18 electrons.
The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6
